To all 'whom it 711mg/ concern.'

Be it known that we, DANIEL ll. GAIL and JOHN F. GAIL, both of Brooklyn,in the county of Kings and State of New York, have invented certain newand useful Improvements in loven-lire Mattresses and Seats, duc.; and wedo hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying' drawings, and to theletters of reference marked thereon, making a part of thisspecification.

Our invention relates, primarily, to the manufacture of woven-wiremattresses or bed-bottoms, and has for its object to simplify theconstruction thereof, and to produce at the least possible cost athoroughly durable and elastic portable metallic mattress, said in'vention being likewise applicable to the manufacture of elastic seatsand backs for sofas, chairs, tir-c.; and it consists in the details ofconstruction and combination of parts here inafter described andclaimed.

In the accompanying drawings, Figure l is a view in perspective ofoui-improved double metallic mattress; Fig. 2, a plan view of the underside of one end thereof; Fig. 3, a detail, on an enlarged scale, of aportion, of the top thereof; Fig. et, an elevation in perspective of oneof the spiral springs detached; and Fig. 5, a detail, on the sameenlarged scale, illustrating in elevation 011e of the springs wheninterposed and secured in position between the two faces of the mattressin accordance with our invention. Fig. (5 is a plan view broken away,showing the manner of hinging the upper frames and apply:Y

ing the transverse tie-wires.

The improved double mattress is construct ed of an upper facing orsection, A, which is made to extend in an unbroken sheet from side toside of the bed, and of two longitudinal lower sections hinged togetherlengthwise by means of the upper section, to which they are attached.Each of these sections A and O C is formed of spiral-wire strandsinterwoven in the manner well known to the art to constitute a iiexibleand elastic metallic sheet, the spiral coils being made to runlengthwise thereof in the usual manner.

The unbroken upper facing or section, A, of woven wire, is stretchedupon two metallic frames, B B, each of which is formed of a single ironbar bent to inclose three sides of a rectangle, the fourth side beingleft open. It is re-enforced and elastically stayed by means oftransverse spiral coils G G, of wire, extending at intervals from sidet-o side thereof at right angles with the longitudinal interwovenstrands of the sheet. Said transverse spirals are preferably carriedAthrough transversely within the interwoven. coils of the longitudinalstrands, as shown in Fig. 5, so as not to project beyond the same oneither face, leaving the inner as well as the outer face smooth andeven. By this transverse arrangement of the spiral coils or wires G Gthe longitudinal wires of the web are supported at regular intervals.The web will thus yield to the shoulder, hips, or other projections ofthe body and yet lie close to and support the rest of the body andaccommodate itself to all the undulations thereof, which, it isapparent, is not the case with longitudinal wires. The transversearrai'igement of the spiral coils or wire, it will be apparent, willalso brace and strengthen each half of the mattress, and thereby alsostrengthen the hinge-connection between the parts by connecting in thecontinuous web with the central longitudinal cord or wire.

The two frames B B are placed so as to bring their open sides, oppositeeach other at the middle of the woven-wire sheet A, at which point theends of the wire frames B B are bent inward and enter adjacent coils ofthe woven web a, as shown in Fig. l, which thus becomes a hinge for saidframes B B, so that they may be folded over on said middle line e e, oneupon the other. (See dotted lines, Fig. l.)

The lower face of the double mattress or bed-bottom is made up in twosections, C O', of equal dimensions, correspoi'iding each to one-half ordivision of the upper section, A. Each of these lower sections, C l', isconstructed of a metallic frame formed of an iron rod or bar, D, bentinto a rectangular form, and upon which is stretched the interwovenwires forining the section, and which are made fast to the frame in anysuitable manner. Each lower frame is `17e-enforced and stiffened by aseries of straight rigid IOO transverse rods or tie-wires, K K,extending at regular in tervals centrally within the coils from one sidebar to the other and secured to cach, as shown in Fig. 2. The divisionbetween these two lower sections coincides with the central line, e c,Fig. l, upon which the upper unbroken section, A, folds on hinges, sothat the one lower section, C, maybe folded over upon the other, C', onsaid line, and when thus superimposed their edges will coincidethroughout.

The upper and lower sections, A and C C', are united to form themattress by means of interposed double helical springs F F F.

Loops H H (see Fig. 4) are formed at diametrically-opposite points onthe outer coils of each of said helical springs F to project betweentheturns of the coiled strands of the mattress when the spring restsagainst or upon the same, as shown in Fig. 5, and the springs aresecured to the lower sections of the mattress or bed-bottom by means ofthe straighttransverse rods or tie-wires K K, which are made to engagethe loops H H, and to the upper section by means of the spiral strandsor reentorcing coils G, of'wire, run through and within the interwovencoils ot' the longitudinal spiral strands of said section transverselyacross the section, and which engage the loops H H of the opposite endof the springs, as shown in Fig. 5. The springs F F are thus securelytied to the upper and lower sections, A C C', of the mattress, so thatthey may not be displaced or overturned and operate to bind the sectiontogether.

. It will be apparent that the arrangement of the transverse tie-rods Kor spiral coils l may be reversed or that one may be used in lieu of theother.

le contemplate the use of our invention in the seats and backs of sofas,lounges, &c., as well as for beds.

le claim as our inventionl. The combination, in an elastic wovenwiremattress or bed-bottom, of the unbroken or continuous upper-section, A,of interwoven Wires, the two frames B B, supporting the same and havingthe inturned meeting ends entering and engaging coils of said uppersection and forming a hinge, whereby the bedbottom maybe folded, the twoseparate lower Y sections, C C', of similar wires, the interposed spiralsprings connecting said upper and lower sections, substantially as andfor the purpose described.

2. rlhe combination, in an elastic wovenwire mattress or seat, of thecontinuous or unbroken upper web of interwoven spiral wires, thetwo-part wire frame upon which the same is stretched, and the transversere-enforcing spiral coils or tie-wires formed in two sections, eachunited at one end to the wire frame and extending th rough the coils ofthe woven-wire web and attached to the central cord or wire thereof,substantially as specied.

The combination, in an elastic wovenwire mattress or seat, of thewoven-wire facing, the helical springs having loops H H projecting fromtheir outer coil, and the tie-wires carried transversely through saidloops and within the spiral coils oli' the woven-wire facing, wherebythe sprin gs are connected to said facing, substantially in the mannerand for the purpose set forth.

4. The combination, in an elastic wovenwire mattress or seat, of the twoouter facin gs severally formed of metallic frames an d woven wiresstretched upon said metallic frames, the interposed helical springshaving loops H ll projecting from their-outer coils to pass in betweenthe coils of the woven wires, the transverse straight tie-wires passingthrough the coils of one of said facings and engaging the loops at oneend of the springs, and the spiral tie-wires passing centrally andtransversely through the coils of the woven wires and the loops at theopposite ends of said springs, all substantially in the manner and forthe purpose herein set forth.

5. The combination, in a wover-wire bedbottom, of a frame, a continuouswoven-wire fabric attached thereto, andre-enforcingwires,.

spiral coils, or rods separate therefrom, running transversely of saidbed-bottom, secured at their ends to said frame, and connectedto thefabric by engaging the coils thereof, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing Witnesses.
